TLDR
In this article, the problem of unbiased estimation of a finite population proportion and compare the relative efficiency of the unequal probability sampling strategies due to Horvitz and Thompson (1952) and Murthy (1957) under a super-population model was considered.Abstract:
We consider the problem of unbiased estimation of a finite population proportion and compare the relative efficiency of the unequal probability sampling strategies due to Horvitz and Thompson (1952) and Murthy (1957) under a super-population model. It is shown that the model expected variance is smaller for the Murthy's (1957) strategy both when these two sampling strategies are based on data obtained from (i) a direct survey, and (ii) a randomized response (RR) survey employing some RR technique following a general RR model.read more

TL;DR: In this paper, two sampling schemes are discussed in connection with the problem of determining optimum selection probabilities according to the information available in a supplementary variable, which is a general technique for the treatment of samples drawn without replacement from finite universes when unequal selection probabilities are used.

Randomized response: a survey technique for eliminating evasive answer bias.
TL;DR: A survey technique for improving the reliability of responses to sensitive interview questions is described, which permits the respondent to answer "yes" or "no" to a question without the interviewer knowing what information is being conveyed by the respondent.

An alternative randomized response procedure
TL;DR: In this article, a new randomized response procedure was proposed, which requires the use of two randomization devices, and the conditions when the proposed strategy will be more efficient than the usual Warner's strategy have been obtained for the cases when the respondents are truthful and when they are not completely truthful in their answers.

Asking sensitive questions indirectly
TL;DR: In this paper, the authors proposed a new method for conducting surveys on sensitive topics which does not require direct answers from the respondents. But it overcomes some difficulties associated with traditional randomized response techniques and is applicable to both qualitative and quantitative characteristics.
